Put the slut injection into her coffee and put the dildo on the desk

You empty the contents of the syringe into her coffee and place the dildo right in the middle of the desk.

You hear footsteps in the hall so you dart into the closet.

She enters and looks puzzled. She closes the door behind her and has a sip of coffee.

She reaches out to put the dildo away, but immediately puts it back in place.

She climbs up onto the desk and pulls her panties to the side, before hovering over the dildo.

She begins riding it and Agent 69 gets the whole thing on video.
